Figure 6
(a) Reciprocal-space map and (b) the corresponding peak profiles of the 023 reflection at 10 K. The horizontal axis of (a) is the direction of the ω–2θ scan (direction of the diffraction vector) and the vertical axis of (a) is the offset in the ω-scan direction [∊ = (2θ /2) − ω]. The map was taken at the non-bisecting setting, i.e. ω ≠ θ. The color scale is logarithmic to base 10. |
